Description
Technical field
The present invention relates to a kind of gas pipeline cleaner, especially relate to a kind of combustion gas and use the buried pipeline deduster.
Background technology
In the conveying of use buried polyethylene pipeline, in the low pressure natural gas,,, often have solid granulates and exist because it is not thorough at polyethylene pipe post-purge to be installed though require the quality of gas to be up to state standards.Polyethylene pipe maybe the old steel pipe of seriously corroded be connected with service life is long, and therefore, inevitably causing has the small amount of solid state particle to exist in the pipeline.If with polyethylene pipe transportation of liquefied oil gas, artificial coal gas, also may have liquid particles in the gas.These solid-state or liquid particles can be worn and torn ducted polyethylene ball valve and cause in the ball valve and leaked, the instrument and meter in also maybe blocking pipe.Therefore, in polyethylene pipe, be badly in need of installing cleaner.
The present invention has carried out useful improvement in order to overcome above-mentioned defective.
Summary of the invention
The objective of the invention is to solve above-mentioned deficiency of the prior art, provide a kind of simple in structure, be skillfully constructed, the easy to operate deduster of combustion gas that can be used for the buried polyethylene pipeline.
To achieve these goals, the present invention adopts following technical scheme:
A kind of combustion gas is with buried polyethylene pipeline deduster, and its design feature is that said combustion gas comprises dust storage container and delivery pipe with buried polyethylene pipeline deduster, and said dust storage container is cylindrical; Dust storage container inside is hollow structure; Position, middle and upper part in the dust storage container side is provided with air inlet, is provided with the gas outlet at dust storage container top center position, and the dust storage container air inlet is connected with the fuel gas polyethylene admission line through the air inlet flange; The dust storage container gas outlet is connected with first intermediate conduit through the gas outlet flange; The end of flange head is provided with concave station in the gas outlet, and screen pack is installed on concave station, and said delivery pipe inserts dust storage container from the dust storage container top inner; And the part that dust storage container is advanced in the insertion of delivery pipe is inserted into the bottom of dust storage container inner chamber, is provided with the copper ball valve in the upper end of delivery pipe;
Further; Adopt the steel flange sheet between two air inlet flange heads of said air inlet flange; Connect through bolt, described air inlet flange head adopts polythene material to process, and employing electric smelting or hot melting way are connected between said air inlet flange head and the fuel gas polyethylene admission line;
Further, said dust storage container and delivery pipe adopt polythene material to be made, and adopt the electric smelting mode to connect between said dust storage container and the delivery pipe, and said copper ball valve and delivery pipe adopt mechanical connection;
Further; Adopt the steel flange sheet between said two gas outlet flanges; Connect through bolt, the said gas outlet flange head and first intermediate conduit all adopt polythene material to process, and said gas outlet flange head is connected through hot melt or electric smelting mode with first intermediate conduit;
Further; Said first intermediate conduit is connected with an end of first elbow; The other end of said first elbow is connected with second intermediate conduit; The other end of said second intermediate conduit is connected with second elbow, and the other end of said second elbow is connected with the fuel gas polyethylene outlet pipe, and described fuel gas polyethylene outlet pipe and fuel gas polyethylene admission line are installed on the same axis in the horizontal direction;
Further; Said first elbow, second intermediate conduit, second elbow are polythene material and process, and the connection between said first intermediate conduit, first elbow, second intermediate conduit, second elbow all adopts electric smelting or hot melting way to connect.
Explain: described first elbow and second elbow are two elbows that are installed in different parts in order to distinguish, and described first intermediate conduit and second intermediate conduit also are two pipelines that are installed in different parts in order to distinguish.
When the natural gas that has solid-state or liquid particles gets in the dust storage container through fuel gas polyethylene admission line, air inlet flange head; Because it is big that the space becomes suddenly; Gas flow rate descends; Thicker solid-state or liquid particles is changed under the centrifugal force double action that produces at gravity and gas flow, at first deposit to the dust storage container bottom.Consider that possibly have few parts of fine granule does not deposit, this deduster has been installed screen pack at the outlet(discharge) flange place of dust storage container.After pipeline stabilization operation a period of time, the solid-state or liquid particles that is deposited on the dust storage container bottom can increase, and can open the copper ball valve this moment, solid-state or liquid particles can the gas pressure effect in dust storage container under, along with delivery pipe is discharged to the deduster outside.
Beneficial effect of the present invention: through in the fuel gas polyethylene pipeline, deduster being set; Can effectively remove the particle in the pipeline; Gas pipeline and ball valve are played a very good protection, also protected the instrument and meter of pipeline, guaranteed the unimpeded of combustion gas transmission.
